HEDDLE FRAME Filed Jan. 28, 1932 Patented Aug. 23, 1932 unirse 1 stares i rarest' erstes LQU'IS RQEACKER, OF'FREEPORT, lILIVIQINOIS, ASSIGNOR TO STRUCTO MANUFACTUR- NG- CGMEANY, F FREEPORT, IIILIJIN'OIS, A CORPORATION OF ILLNOIS HEDDLE FRAME v Appunti@ mea January 28, 1932. serial No. 589,339.

This invention relates vto heddle frames for looms, and its principal object is to provide simple and efficient means for attaching and locking the heddles to the frame.

Another object is to provide novel means whereby any number ofl the heddles may be quickly detached from the frame or others added to those already carried thereby.

lVith thes-e and other objects and advan-l 'lo tages in view, this invention consists in the several novel features of construction,` arrangement and combination of .parts hereinafter fully set forth and claimed.

The invention is clearly illustrated in the "V1.5 drawing accompanying this specification in which-- y Figure 1 is a. side elevation of a heddle frame embodying` a simple form of the present invention, and illustrating a number of 2c heddles attached thereto, the heddle frame being shown in connection with a fragment of the framework of a loom;

Fig. 2 is a side elevation of the heddle frame and heddles illustrating the manner '25 of disconnecting the locking bars from the frame;

Fig. 3` is a view similar to Fig. 2, illustrating the manner of removing or replacing any of the heddles;

F 4 is a detail vert-ical cross section taken on the line Llof Fig. 1; and

Fig. 5 is a detail vertical cross section taken on the line 5 5 of Fig. 1.

Referring to said drawing, the reference character 6 designates a fragment 0f the framework of a loom of ordinary construction, and 7, 7 designates upright guides or channels in which the heddle frames are guided for vertical movement.

The heddle frame comprises upper and lower horizontal frame bars 8 and upright frame bars 9 extending between the ends thereof and spot welded or otherwise secured thereto to form a rectangular frame. To 'r' the upper horizontal frame bar 8 are secured loops or eyes 10 in which are removably secured the bent ends of a bail 11 which is connected by suitable means to operating mechanism for separating the heddle frames, but as this mechanism forms no part of the 'present invention, it will not be necessary t0 describe the same. rlhe upright frame bars 9 are desirably channel shaped or U-shape in cross section, theside webs 12 of which overlap the upperand lower bars 8 and are Y spot welded thereto, and the U-bends 13 of which are slotted at their upper and lower ends as at 14 and 15.

Removably held in the slots 14C and 15 are upper and lower heddle locking bars'16 and 17, one of which has interlocking connections with the upright `frame bars, and for this purpose is provided with notches 18 adjacent its ends adapted. to engage over the edges of the' associated slots 14 in theupright frame bars 9. The heddles 19 are formed with slots adjacent` their upper and lower ends through which the locking bars 16 and 17 extend, and, in accordance with common practice, are also provided with eyes 2O intermediate their ends through which the warp threads are threaded.

It will be observed that the interlocking connections between the` upper locking bar 16 and upright frame bars 9 prevent endwise movement of said locking bar, and that when the'lower locking bar is held in the slots 15 with the heddles attached to the locking bars, the upper locking bar cannot be raised to disconnect the notched portionsl from the upright frame bars. When the heddle frame is in place in the guideways 7, endwise movement of the lower locking bar 17 is prevented by the bottoms of the guideways, consequently, the heddles and locking bars are held against disconnection from the heddle frame.

To remove or replace any of the heddles, the bail 11 is detached from the heddie frame, the latterwithdrawn-from the guideway 7 and the lower locking bar 17 withdrawn from one of the slots 15, whereupon the corresponding end of the upper lockingbar 16 may be raised sufficiently to disengage the notched portion 18 from the edge of the slot 111. With the heddles occupying a grouped position at the middle of the locking bars or disposed adiacentthe free ends thereof, the locked end of the upper locking bar may be raised to disengage the notched part from the edge of the associated slot and the upper locking bar may then be slid back, thus withdrawing its opposite end troni the associated upright frame bar, as seen in Fig. 8, thereby permitting any of the heddles to be detached from or others attached to the locking bars. rllhe heddle 19, shown by the dotted lines, in Fig. 3, illustrates the position of one of the heddles about to be attached to the locking bars.

To lock the heddles to the traine, the free end of the upper locking bar is inserted into the slot land both notches re-engaged with the edges of the slots, the free end of the lower locking bar being then inserted into the slot l5. lt will be observed that as long as the lower locking bar is held in the lower slots, the upper locking bar cannot be raised or disconnected troni the upright traine bars, and, as a consequence, the heddles are locked to the traine.

I claim as new,'and desire to secure by Letters Patent:

l. A heddle 'traine in which is comprised a rectangular trarne, horizontal upper and lower locking bars, one of which has interlocking connections with the traine and the other of which has a sliding connection therewith, and heddles removably attached to said locking bars and co-operating therewith to maintain said interlocking- Yconnection between the locking bar and ranie.

2. A. heddle traine in which is comprised horizontal upper and lower traine bars, upright end frame bars rigidly secured thereto to forni a rectangular trarne, said end traine bars having oppositely disposed slots at their upper and lower ends, horizontal upper and lower locking bars, heddles attached to said locking bars, one of said locking bars extending through two oppositely disposed slots in the end traine bars and having interconnections therewith, and the other locking bar extending through the other two oppositely disposed slots and acting through the heddles to hold the other locking bar against disconnection from the trame.

3. A heddle traine in which is comprised horizontal upper and lower trarne bars connected at their ends by uprightr end trame bars, said end trarne bars having oppositely disposed slots adjacent their upper and lower ends, horizontal upper and lower locking hars, heddles having slots at their ends through which said locking bars extend, one ot said locking bars being torined with notches adjacent its ends adapted to engage with the edges of two opposite slots in the end traine bars, and the other locking bar being arranged to extend into the other opposite slots of the upright 'traine bars, whereby to hold the notches oit' the notched locking bar in engagement with the end trarne bars through the heddles.

4. A heddle trarne in which is comprised horizontal upper and lower trarne bars, up-

right end trame bars rigidly secured thereto to form a rectangular traine, said end trarne bars being of channel formation and having oppositely disposed slots at their upper and lower ends, horizontal upper and lower loching bars, heddles attached to said locking bars, one of said locking bars extending through two oppositely disposed slots in the end frame bars and having interconnections therewith, and the other locking bar extending through the other two oppositely disposed slots and acting through the heddles to hold the other locking bar against disconnection from the traine.

5. A heddle traine in which is comprised horizontal upper and lower frame bars connected at their ends by upright end trame bars of channel formation, said end frame bars having oppositely disposed slots adjacent their upper and lower ends, horizontal upper and lower locking bars, heddles having slots at their ends through which said lockingbars extend, one of said locking bars being formed with notches adjacent its ends adapted to engage with the edges of two opposite slots in the end frame bars, and the other locking bar being arranged to extend into the other opposite slots of the upright trarne bars, whereby to hold the notches of the notched locking bar in engage-ment with the end Jframe bars through the heddles.V
